4 Claims.

My invention relates to a novel form of selfiilling fountain pen provided with a pumping arrangement in the cap of the pen, and providing large-capacity for ink in the barrel of the pen. A Referring to the accompanyingdrawing, I have illustrated in Fig. 1 in longitudinal section a suitable form of pen embodying an application of my invention. Fig. 2 is a similar view of the pen in closed position. 3 indicates the barrel of the pen provided with the usual feed plug 4, pen point 5, and air tube I extending from -the feed plug l through the center of the barrel as shown.

l indicates a suitable form of rubber bag anchored at 8 in the internally and externally' threaded nipple 9, secured in the end of the bar- .rel 3 asshown, and III indicates a suitable form of valve which may be turned for controlling the passage of air into and out of the rubber bag 1. I I indicates the cap of the pen which may be provided wlth the usual pocket clip I2, and this cap' is preferably threaded as shown at i3 for engaging the threads Il at the other end of the barrel when the pen is not in use. Within the outer end of the cap II is secured a housing I5 for the pen 5 when not in use, and this housing has a vent 23 at the end and is surrounded by the tube or plunger I8, having a coiled spring Il compressible between the top of the housing I5 and rotatable cap I8 when the plunger I6 is depressed by pressure upon the said cap I8, said cap having a circular flange I9 which is interrupted at points to allow the same to engage beneath a similarly interrupted lflange 20 at the top of the ring 2| in the top of the cap I I, so that when not in use, the plunger I6 may be depressed andthe cap I8 may be turned to engage beneath the flange 20, thereby holding the same in closed position, the pen 5 passing within the housing I5 and being protected thereby.

In operation, after the cap I8 has been released by turning the same to clear the flange 20,

the plunger I6 is projected outwardly until the' circular flange 22 thereof strikes the filler ring 2| serving as a stop to limit the projection of the plunger I6. By now depressing the plunger, air within the housing I5 is forced beneath the valve I0 and into the collapsed bag 1, said bag having previously collapsed by the outward pro- 5o jection of the plunger I6. The expansion of the bag 1 now forces .air down through the tube 6 and out beneath the pen 5. Upon vreleasing the plunger I6, the air in the expanded bag 1 is now exhausted and the bag collapses, drawing ink from a suitable well upwardly through the filler plug 4 into the barrel 3, and upon again depressing the plunger I6, the bag 'I again inilates, and air is again discharged through tube B beneath 'pen 5, and so on 'until the barrel l is sub- 5 stantially filled with ink.

A suitable cut or passage 2l may be provided to allow for the escape of air when applyingthe cap Il, and of course, various modifications may be made in the construction and arrangement of 10 parts without departing from the spirit of the l invention as claimed.A

I claim:

1. A fountain pen with ink charging mechanism comprising a tubular body portion, means 15 for retaining the pen in one end thereof, a sac and valve therefor within the opposite end thereof, a removable capV adaptedto be secured over said last mentioned end, a pen housing in said cap and a spring projected plunger pump operative 20 externally of said housing and, from the "end of said cap. f Y f 2. A fountain pen with ink charging mechanism comprising a tubular body portion, means ,for retaining the pen in one end thereof, a sac 25 and valve therefor within the opposite end thereof, a removableV cap adapted to be secured over said last mentioned end, a pen housing in said cap and a spring projected plunger pump operative externally of said housing and from the end 30.

o f said cap, said spring concentric with said housing and cap and between the same.

3.A fountain pen with ink charging mechanism' comprising a tubular body portion, means for retaining the pen in one end thereof, a sac 35 and valve therefor within the opposite end thereof; a removable cap adapted to be secured over said last mentioned end, apen housing in said cap and a spring projected plunger pump operative externally of said housing and from the end 40 of said cap, said valve adapted to be closed when v said pen is used, .and to beopened when charging the same with ink.4

4.. A fountain pen `with ink charging mechanism comprising a tubular body portion,A means 4,5 for retaining the pen in'one end thereof, a sac and valve therefor within the opposite end thereof, a removable cap adapted to be secured over said last mentioned end, a pen housing in said cap and a spring projected plunger pump operative externally of said housing and from the end of said cap, and means for locking' said pump within said cap when not in use.
